ABSTRACT:
A food processor is comprised of a food processing cutter which is driven by a motor connected to an AC power source, a switch for controlling on and off of the motor, a pulse generator for forming count pulses having a given period from the AC power source, a set switch, a start switch, and a timer which operates the start switch at a time point set therein to start the rotation of the motor. Further, the food processor includes an up-counter for counting the count pulses while the set switch is operated to store a driving time period data of the motor, and a down-counter to which the stored data of the up-counter is transferred when the start switch is operated by the timer. The down-counter counts down the data every time it receives the count pulse and produces a drive stop signal for the motor when its contents become "0".
